Give that man a Ceegar! They don't need to have mastered the rules any more than casual players...but they do need to be actively playing and helping things along. I rarely keep a creature's AC a secret more than a round or so...with six PCs, they can usually narrow the range very quickly. "Let's see, I hit three times, getting a 44, 40 and 36, but missing on a 32 and 31....well, that narrows it down, some."ruleslawyer said:Then I relaxed, and let the players figure out all applicable modifiers. Guess what? The game got terrifically easy for me. A player rolls, does his own math, and tells me what the result was; I compare it to the applicable AC or DC, and it's either a success or failure. Easy-peasy.
I don't bother tracking all the bonuses the PCs have...they can take care of that. "Did you remember to add the bonus from Prayer?" "Hey, aren't you blinking?" I respect and trust my players.
I wouldn't consider it expecting rules mastery to read a spell description ahead of time and compute the DC of your spell, ready to report it when asked. I don't consider it a lot to ask to expect a PC to know his attack bonuses prior to proximate factors or what his ranges and other relevant information are. I'd expect that at 1st level, 5th level or 20th level. Players don't suddenly wake up and find themselves with three more iterative attacks one day...they've developed into them, generally. Asking someone who's played a rogue for 5, 10, 15 or 20 levels about when he can use his sneak attack and how much they do isn't unreasonable, I don't think.
High-level play isn't about pulling tight on the reins, IMHO, but about letting the PCs drive the game with you. It's a social and cooperative game. Looking to the other folks around the table to help keep the game moving is a wise thing.
